DAVID OLMS TED, OF MINNEAPOLIS, MINNESOTA.

FLUlD-RELEASING DEVICE.

SPECIFICATION" forming part of Letters Patent No. 405,320, dated June 18, 1889.

Application filed March '7, 1889- Serial No. 302,228. (No model.)

verse vertical section of my device. Fig. 2 is a detail section on line 00 cc of Fig. 1. Fig. 3

is a detail section on line y y of Fig. 2.

In the drawings, 2 represents a suitable airtight tank or receptacle.

3 represents a suitable chamber open at its upper part and communicating by an opening at with the lower part of the receptacle 2. A faucet 5 communicates with the chamber 3, the inner end of the tube of the faucet being preferably in line with the opening 4 between the chamber 3 and the tank 2. A valve 6, provided with a valve-stem 7, is arranged in the faucet-tube 5, the valve closing the inner end of the tube. A spring Sis arranged upon the stem 7 and tends to hold the valve normally closed. A hollow stem 9, having therein a transverse slot 10, engages the end of the valve-stem 7. A stem 11 is inserted into the outer end of the tube 9 and is provided with a button or hand-piece 13. A lug or stop 16 is arranged below the slot in the tube 9. A coin-conduit 15 is arranged above the tube 9 in position to direct a coin that is inserted into the conduit into the tube 9.

The operation of this device is as follows: The air-tight tank 2 being filled or partially filled with liquid, a portion of it will run out into the chamber 3. -The atmospheric pressure upoh the surface of the liquid in the chamber 3 prevents more than a small quantity of liquid from escaping from the tank into the chamber 3. This liquid cannot be drawn from the chamber 3 except by opening the valve 6.

This valve cannot be opened until a coin of a predetermined size has been inserted into the conduit 15 and by it conducted into the slot in the tube 9. If there is no coin in this slot, pressure upon the button 13 will merely cause the tube 9 to telescope upon the stem 7 WVhen there is a coin in the slot 10, it prevents the tube from telescoping upon the stem, and pressure upon the button 13 will cause the valve 6 to open, permitting the water in the chamber 3 ,to run out through the tube 5. Then the valve 6 opens the tube 5, it will close the opening 4, leading from the tank 2 into the chamber 3. Asthe valve 6 is opened, the coin will move with the tube 9 sliding over the stop 16. When the button 13 is re leased, the coin will drop out of the slot in the tube 9 and the spring will close the valve. The water will again rise in the chamber 3 until it reaches the point at which it will be stopped by the atmospheric pressure.

It will be understood that the mechanism, with the exception of the button 13 and the end of the conduit 15,will be inclosed in a suitable casing.

I claim as my invention- 1. The combinatiomwith an air-tight tank, of a chamber communicating with the lower part of said tank and open at its top to permit the pressure of the atmosphere upon liquid in said chamber, a valve controlling the passage of liquid from said chamber, and a coinoperated mechanism governing said valve, substantially as described.

2. The combination,with the air-tight tank 2, of the chamber 3, provided with the opening 4, communicating with said tank, the faucet-tube 5, connecting wit-h said chamber 3, the valve 6, arranged to close said tube, the spring 8, and the tube 9,provided with a coinreeeiving slot 10, substantially as described.

In testimony whereof I have hereunto set my hand this 4th day of March, 1889.

DAVID OLIWISTED.
